Climatic Change

States climate in India has large spatial and temporal variations due to its vast size and geography

Finds that in the last century the atmospheric surface temperature in India has enhanced by about 1 and 1.1°C during winter and post-monsoon months respectively, according to observed data and model reanalyzed fields

Finds that observations indicate occurrence of more extreme temperature events in the east coast of India in the recent past

Finds that during summer monsoon months, there is a decreasing (increasing) trend in the frequency of depressions (low pressure areas)

Finds an increase in the number of severe cyclonic storms crossing Indian Coast

Analysis of rainfall amount during different seasons indicate decreasing tendency in the summer monsoon rainfall over Indian landmass and increasing trend in the rainfall during pre-monsoon and post-monsoon months
